image is the main component of printing, and image detection technology has naturally become the key technology of printing detection. In view of this, this paper first introduces the key parts, applications and advantages of machine vision technology and its system. Secondly, it introduces its application in the printing quality inspection system, which makes it possible to import waste paper into waste pulp overseas. Finally, its application in banknote printing quality inspection process is emphatically introduced

I. Introduction to machine vision

machine vision is an interdisciplinary subject involving artificial intelligence, neurobiology, psychophysics, computer science, image processing, pattern recognition and other fields. It is not only an extension of medalist MD 12445 compound with a shore a hardness of 45 human eyes, but also has part of the function of human brain. In recent years, with the maturity of computer technology, especially multimedia technology, digital image processing and analysis theory, and the rapid development of large-scale integrated circuits, machine vision technology, especially in product recognition and industrial detection, has been widely used and studied, and has achieved great economic and social benefits

1. The key part of machine vision system

a, machine vision products; B. Ingested target; C. Image signal; D. Various image processing operations; E. Image features; F. Discrimination results; G. Automatic control

Figure 1 general process of machine vision system

2. Application scope of machine vision system

is widely used in the fields of working condition monitoring, finished product inspection and quality control. Machine vision system improves the flexibility and automation of production. Using machine vision detection method can greatly improve the production efficiency and automation of production

3. Advantages of machine vision

a. machine vision is based on objective analysis and reasoning. It effectively avoids the subjectivity and individual differences caused by manual detection, and improves the detection accuracy

b. it can improve the detection speed

c. large short-term investment, but the average cost of long-term use is lower than manual detection. In particular, with the continuous development of related technologies, the detection speed has increased rapidly, and the detection cost has continued to decline

d. it is convenient to store, process and analyze the test data, and provide suggestions and guidance for the subsequent production of products
